Export or back up messages, calendar, tasks, and contacts

To transfer your messages, calendar, tasks, and contacts to Outlook on another computer or to make a backup, export the information to an Outlook Data File (.pst).

Click File > Open & Export > Import/Export.

Click Export to a file, and then click Next.

Click Outlook Data File (.pst), and then click Next.

Select the account you want to export by clicking the name or email address, such as Mailbox – Anne Weiler or anne@contoso.com. If you want to export everything in your account, including mail, calendar, contacts, tasks, and notes, ensure the Include subfolders box is checked.

Note You can export one account at a time. If you want to export multiple accounts, after one account is exported, repeat these steps.

Click Next.

Click Browse to select where to save the Outlook Data File (.pst) and to enter a file name. Click OK to continue.

Note If you’ve used export before, the previous folder location and file name appear. Type a different filename before clicking OK.

If you are exporting to an existing Outlook Data File (.pst), under Options, specify what to do when exporting items that already exist in the file.

Click Finish.

Outlook begins the export immediately unless a new Outlook Data File (.pst) is created or a password-protected file is used.

If you’re creating an Outlook Data File (.pst), an optional password can help protect the file. When the Create Outlook Data File dialog box appears, enter the password in the Password and Verify Password boxes, and then click OK. In the Outlook Data File Password dialog box, enter the password, and then click OK.

If you’re exporting to an existing Outlook Data File (.pst) that is password protected, in the Outlook Data File Password dialog box, enter the password, and then click OK.
